Heya everyone,

I've been searchin online for an answer to my issue. My current project is going to feature a lot of rollover buttons, something that doesn't exist as an ASP.NET control. Obviously that left me a market to make one!

I made a quickie one (it is very simple, with a postbackurl, target, and 3 image url's).

I'm trying to do something that I've never done before, however. I'm new to WebControl development, and I want the URL properties (for defining the image on hover, normal, and down), to pop-up that familiar box that allows you to select files from your website. How can I implement that?
